Coal-fired boilers HRSG Product Applications: Using the efficiency of industrial oil, gas, coal-fired boiler is about 70%, in the waste heat in the flue gas accounted for most of the heat. Typically hot water, steam boiler flue gas temperature above 200 degrees, oil furnace flue gas temperature 270--350 degrees. Such high temperatures not only pollute the environment, but also waste a lot of fuel, increasing production costs. The product is the use of this part of the heat pipe heat recovery. Use to improve boiler feed water, blast temperature, or direct steam generation scour Heat Pipe end, the heat pipe working fluid evaporates into a gas flow to the cooling side, cooling side condensing heat, water or air is heated to produce hot water hot air and steam. That is, the products are widely applied to clothing, food, textiles, packaging, pharmaceuticals, metallurgy and other industries of coal-fired boilers. Complete specifications, but also production orders. Exhaust gas temperature of 200 degrees around the coal-fired boilers are applicable. Product Principle: heat pipe heat exchanger core manufacturing technology. Heat pipe is a heat transfer element having high conductivity properties, which closed in the vacuum envelope by the working fluid evaporation and condensation to transfer heat, with a high thermal conductivity, good heat transfer and other warm, hot and cold sides of area can be arbitrarily changed, the heat transfer can be remote, you can control the temperature of a series of advantages. Installed on the boiler flue, recycling waste heat is used to heat water to produce steam. Its construction is the lower flue, the upper part of the tank, the middle separator tank has water interface, a vapor interface and outfall, the upper part of the tank for the drum. In operation, the flue gas flows through the heat pipe heat back to the lower end of the heat pipe flue scouring, heat pipe to the upper end of the guide after absorbing the heat, the upper end of the heat pipe heat water to generate steam heated to a certain temperature. This equipment remarkable energy savings, fuel savings of 10-30%. Features: 1. High boilers fired boilers heat transfer efficiency, the volume is the same level of heat 1/2? ? , Ventilation resistance, thereby saving blower and induced draft fan power consumption. 2. Heat Pipe rely phase transition pipe working fluid conducted heat pipe sealed at both ends by the end caps, when the side wall of a heat pipe is perforated inner tube, only a small amount of working fluid leakage, but heat? Body not collusion, and therefore greatly reduces the possibility of air leakage. 3. isothermal heat transfer characteristics of the heat pipe wall can guarantee the flue gas temperature is maintained at a temperature above the dew point, so always ensure that the heat pipe wall temperature can be maintained at a temperature above the dew point of the flue gas, gathered? ? In the wall of the soot is basically dry ash, flue gas velocity fluctuations when the wind away, to form a self soot blowing process. At the same time, the heat generated from the shock tube at work, shake off the ash away with the wind, so that the entire heat exchanger less prone to gray block. 4. By the end of the heat pipe heat exchanger wall flue gas temperature control, can when each of the heat exchanger tubes every point above the dew point, thus effectively fired * dew point to avoid corrosion. 5. The heat pipe heat exchanger is a stationary device with no moving parts, so there is no possibility of mechanical failure. Each heat pipes are relatively independent, can be a single service, even a small amount of the heat pipe is damaged and will not cause leakage or heat load significantly reduced, so that the entire device reliability is very high.
